No Formulas, Just Instructions

Field notes

The workflow accepts CSV, XLSX, and XLS uploads up to 100 MB, then applies a natural-language instruction and returns a new workbook with a summary of the changes. Its examples combine operations in one pass, such as filtering a 48,210-row quarterly sales file down to 3,884 rows while sorting and highlighting values. The service also says excluded rows are preserved on their own tab, and that uploads and results are automatically removed after 14 days.
